Purification of the major envelope protein GP5 of porcine reproductive and respiratory syndrome virus (PRRSV) from native virions
… αORF5 antibody. Cation exchange chromatography (CEX) was utilized for partial fractionation of GP5, although the viral nucleocapsid protein, N, was a major impurity in CEX elution fractions. As a second chromatographic step, hydrophobic interaction chromatography (HIC) further purified GP5 by …

CHAOS: A multi-GPU PIC-DSMC solver for modeling gas and plasma flows
… and slow neutrals that undergo charge-exchange (CEX) reactions to produce slow ions and fast neutrals. These slow CEX ions are strongly influenced by the electric field induced between the ion plume and the thruster surface, resulting in a backflow of ions towards the critical solar panel and …

Production and preliminary characterization of a fusion protein comprising streptavidin and a cellulose-binding domain
The cellulose-binding domain of exoglucanase Cex (CBDCex) from Cellulomonas fimi can be fused to heterologous proteins. The fusion proteins can be purified by affinity chromatography on cellulose or immobilized on cellulose (Ong et al., 1989b). Streptavidin, a protein produced by Streptomyces …

The Heterogeneity of Consumer Behavior: Analyzing Entertainment Expenditures in Relation to Lifecycles, Business Cycles and Demographic Influences
… data from the U.S. Consumer Expenditure Survey (CEX) to explore how entertainment spending patterns differ across various income levels, lifecycle stages, and macroeconomic conditions and how these differences change through time. The first empirical part analyzes the income elasticity of …

Modeling Differential Charging of Composite Spacecraft Bodies Using the Coliseum Framework
… to the DAWN spacecraft. This case showed that CEX ion distribution is not even along the spacecraft and will result in a transverse potential gradient along the panel.

Validation of the DRACO Particle-in-Cell Code using Busek 200W Hall Thruster Experimental Data
… using a projected background neutral density and CEX collision tracking. A stretched mesh was tested and proved results that are as accurate as a uniform mesh, if not more accurate in locations of high mesh refinement.

Analysis of genes and enzymes involved in the degradation of cellulose and proteins by Butyrivibrio fibrisolvens H17c
… similar to the binding domains of the CenA and Cex cellulases from Ceilulomonas fimi The gene expressing cellodextrinase activity (ced1) was cloned on a recombinant plasmid pES500. This gene was located on a 3.55 kb fragment and was also expressed from its own promoter in the E. coli host. The …

A Study of the Consultation and Relational Empathy (CARE) Measure for Medical Students
… as the mini-Clinical Evaluation Exercise (mini-CEX), Objective Structured Clinical Examination (OSCE) at the end of the GP block, and tutor scores (r = 0.38, r = 0.33, r = 0.33, respectively; P < 0.05). The findings suggest that the CARE measure is a useful tool for assessing senior medical …

Characterising epithelial to mesenchymal transition and pro-fibrotic processes in chronic obstructive pulmonary disease
… COPD current smokers (CCS) and COPD ex-smokers (CEX). Identified regions of EMT tissue were laser capture microscopy dissected, RNA isolated, and target genes assessed by Q-RTPCR. Tissue culture experiments were performed by expanding fibroblasts from 1mm lung sections in RPMI culture media that …
